Description
Magnetic interactions in hexaferrite samples of Ba1-xLax+δFe12-xCoxO19 composition were studied. The precursor powders-barium carbonate (BaCO3), lanthanum oxide (La2O3), hematite (Fe2O3) and cobalt acetate-were milled for 100 h in air atmosphere and heat-treated for 1 h at 10000C. The structural characterization was performed by X-ray diffraction. The FORC distributions show a single peak at high switching fields, indicating that the substituted systems are formed by weakly interacting particles. La excess induces the decoupling of the particles
